admin_nodeInfo
Last updated:
`admin_nodeInfo` returns a single object describing the node that handled the call: its node ID, the human-readable client name/version, the `enode` URL used for peering, the IP and ports it listens on, and the set of sub-protocols it supports along with their status.
Use it to confirm which node served a request, to read the node's advertised `enode` for peering diagnostics, or as the anchor point when building a peer graph alongside the other `eth_peergraph` methods.
This is a **business-tier** method in the `eth_peergraph` category. It takes no parameters and is rate-limited to **20 requests per second** with burst.
